How to use await inside a class function?

[Parsoolak]

I'm having some difficulty using Block\await function in reactphp codes. I implemented this issue in 3 ways but either way it failed to do my task!

Number 1

It will execute correctly but it close the connection and stops server

public function awaitLottieResizer($amount, $asset)
    {
        try {
            $fun =  aPromiseFunction(); // it will return PromiseInterface
            return await($fun);
        } catch (\Exception $e) {
            return "Exception";
        }
    }

Number 2

It won't return anything and code stuck but the server is running

public function awaitLottieResizer($amount, $asset)
    {
        try {
            $fun =  aPromiseFunction(); // it will return PromiseInterface
            return await($fun, null);
        } catch (\Exception $e) {
            return "Exception";
        }
    }

Number 3

It won't return anything and code stuck but the server is running

public function awaitLottieResizer($amount, $asset)
    {
        try {
            $fun =  aPromiseFunction(); // it will return PromiseInterface
            return await($fun, React\EventLoop\Loop::get());
        } catch (\Exception $e) {
            return "Exception";
        }
    }

PS: I use React\Http\HttpServer; to create my rest api

PROGRESS REPORT:
I Found the issue
When I Call the awaitLottieResizer function from a promise interface, Ill get the response but when i call it from out of a promise, I Dont Get any response
also when i call it from inside a promise, my inner promise stop and it closed the server

  private function processTradesAndApply($balanceArray, $userId): PromiseInterface
    {
       // Not Work Here
        $S = $this->awaitLottieResizer(100, "IRT");
        
        return $this->appManagerDatabase
            ->createSelectQuery(
                "Trades",
                ['user' => $userId]
            )->then(function ($result) use ($balanceArray, $userId) {
        // Work Here But Stops the Loop
        $S = $this->awaitLottieResizer(100, "IRT");
    };

}

@Parsoolak Thanks for bringing this up! This has been discussed in #20, #44, #49 and others before and this is more or less by design.

As a rule of thumb, mixing blocking and non-blocking code should be avoided. This means these functions should only be used in a blocking application. If you're using a non-blocking application, you should use non-blocking primitives provided by promises and event emitters.

If you're building an HTTP application, here's an example how this can be used with Framework X:

I believe this has been answered, so I'm closing this for now. Please come back with more details if this problem persists and we can always reopen this 👍
